Increased extracellular pressure stimulates colon cancer cell adhesion by activating focal adhesion kinase (FAK) and Src. We investigated the role of the cytoskeleton in pressure-induced inside-out FAK and Src phosphorylation and pressure-stimulated adhesion. We perturbed actin polymerization with phalloidin, cytochalasin D and latrunculin B, and microtubule organization with colchicine and pac...

p53 mutations and loss of heterozygosity (LOH) have been detected in >50% of lung cancers. Wild-type p53 can prevent replication of damaged DNA and promote apoptosis of cells with abnormal DNA. A human adenovirus, ONYX-015, which has a deletion in the E1B region, has shown tumor-specific cytolytic effect in tumor cells with nonfunctional p53 and antitumor efficacy that can be augmented by chemo...
